Description

生体情報測定装置および血圧計Biometric information measuring device and sphygmomanometer
　この発明は生体情報測定装置に関し、より詳しくは、マイクロフォンを備えた外部端末と音波（超音波を含む。）を介して通信を行う生体情報測定装置に関する。また、この発明は、そのような生体情報測定装置を備えた血圧計に関する。 The present invention relates to a biological information measuring device, and more particularly to a biological information measuring device that communicates with an external terminal equipped with a microphone via sound waves (including ultrasonic waves). The present invention also relates to a sphygmomanometer provided with such a biometric information measuring device.
　従来、外部へ音波を発する生体情報測定装置として、例えば特許文献１（特開２００７－３０９７８６号公報）に開示されている電子体温計のように、振動板を含むブザーを備え、内ケースと、この内ケースに対向するブザーカバーとの間に、前記ブザーの振動板を挟み込むように固定したものが知られている。前記ブザーカバーは、外ケース（表示器が設けられた側）の内壁面によって、前記ブザーへ向けて押圧されている。 Conventionally, as a biological information measuring device that emits sound waves to the outside, for example, like the electronic thermometer disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 2007-309786), a buzzer including a diaphragm is provided, and an inner case and the buzzer are provided. It is known that the diaphragm of the buzzer is fixed so as to be sandwiched between the buzzer cover and the buzzer cover facing the inner case. The buzzer cover is pressed toward the buzzer by the inner wall surface of the outer case (the side on which the display is provided).
特開２００７－３０９７８６号公報JP-A-2007-309786
　ところで、最近、本出願人は、生体情報として血圧を測定する卓上式血圧計であって、ハウジング内にブザー（振動部材）を収容し、ブザーの振動によってハウジングの壁面を振動させて音波を発し、マイクロフォンを備えた外部端末と音波を介して通信を行うものを開発している。 By the way, recently, the applicant is a desktop sphygmomanometer that measures blood pressure as biological information. A buzzer (vibration member) is housed in the housing, and the wall surface of the housing is vibrated by the vibration of the buzzer to emit sound waves. , We are developing a device that communicates with an external terminal equipped with a microphone via sound waves.
　ここで、普及型の卓上式血圧計では、ハウジング（血圧計本体をなす筐体）は、略平板状の底壁部とその周縁から上方へ延びる側壁部とを一体に含む下ハウジングと、略平板状の上ハウジングとを組み合わせて構成されることがある。上ハウジングには、表示器および操作スイッチが配置されるため、仮に上ハウジングの内面にブザーを固定して、上ハウジングを振動させる構成を採用すると、振動の伝達状態（つまり、通信状態）が悪くなる可能性がある。特に、上ハウジングの上面がフロント銘板で覆われるデザインを採用する場合は、さらに通信状態が悪化する可能性がある。また、下ハウジングの底壁部は、テーブル等に面するため、音波通信に用いるには不向きである。また、側壁部（縦壁）にブザーを固定しようとする場合、単に上ハウジングと下ハウジングとの間にブザーを挟み込むような固定構造（従来例並みの固定構造）を採用することができず、固定のための新たな工夫を要する。 Here, in the popular desktop sphygmomanometer, the housing (housing forming the main body of the sphygmomanometer) is a lower housing including a substantially flat bottom wall portion and a side wall portion extending upward from the peripheral edge thereof, and abbreviated. It may be configured in combination with a flat upper housing. Since the display and operation switch are arranged in the upper housing, if a buzzer is fixed to the inner surface of the upper housing and the upper housing is vibrated, the vibration transmission state (that is, the communication state) is poor. There is a possibility of becoming. In particular, when the design in which the upper surface of the upper housing is covered with the front name plate is adopted, the communication condition may be further deteriorated. Further, since the bottom wall portion of the lower housing faces a table or the like, it is not suitable for use in sound wave communication. Further, when trying to fix the buzzer to the side wall (vertical wall), it is not possible to adopt a fixing structure (fixing structure similar to the conventional example) in which the buzzer is simply sandwiched between the upper housing and the lower housing. A new device for fixing is required.
　そこで、この発明の課題は、マイクロフォンを備えた外部端末と音波を介して通信を行う生体情報測定装置であって、ハウジングをなす側壁部の内面に振動部材を固定して側壁部を振動させることにより、音波による通信状態を良好に保つことができる生体情報測定装置を提供することにある。また、この発明の課題は、そのような生体情報測定装置を備えた血圧計を提供することにある。 Therefore, an object of the present invention is a biological information measuring device that communicates with an external terminal provided with a microphone via sound waves, in which a vibrating member is fixed to the inner surface of a side wall portion forming a housing to vibrate the side wall portion. Therefore, it is an object of the present invention to provide a biological information measuring device capable of maintaining a good communication state by sound waves. Another object of the present invention is to provide a sphygmomanometer provided with such a biometric information measuring device.
　上記課題を解決するため、この開示の生体情報測定装置は、
　マイクロフォンを備えた外部端末と音波を介して通信を行う生体情報測定装置であって、
　内部に収容空間を有するハウジングと、
　上記収容空間の内部に配置され、受けた信号に基づいて振動する振動部材と
を備え、
　上記ハウジングは、
　面状に延在する第１壁部と、

　上記第１壁部および上記第２壁部に交差して延在する側壁部と
によって上記収容空間を画定し、
　上記側壁部の内側の特定の領域に、上記側壁部と一体の構成要素からなり、上記振動部材が上記側壁部の内面に沿った一方向から圧入され得る隙間をもつ振動部材保持部が設けられ、
　上記振動部材保持部に、上記振動部材が上記一方向から圧入されて、上記振動部材の振動を上記側壁部に伝達させる態様で保持されている、ことを特徴とする。 In order to solve the above problems, the biometric information measuring device of this disclosure is
A biometric information measuring device that communicates with an external terminal equipped with a microphone via sound waves.
A housing with an internal storage space and
It is provided with a vibrating member that is arranged inside the accommodation space and vibrates based on the received signal.
The above housing
The first wall that extends in a plane and
The second wall portion facing the first wall portion and extending in a plane shape,
The accommodation space is defined by the first wall portion and the side wall portion extending across the second wall portion.
A vibrating member holding portion is provided in a specific region inside the side wall portion, which is composed of a component integrated with the side wall portion and has a gap through which the vibrating member can be press-fitted from one direction along the inner surface of the side wall portion. ,
The vibrating member is press-fitted into the vibrating member holding portion from the one direction, and is held in such a manner that the vibration of the vibrating member is transmitted to the side wall portion.
　本明細書で、「音波」とは、空中を伝播する弾性波を指し、人間の可聴周波数（２０Ｈｚ～２０ｋＨｚ程度）より高い周波数をもつ超音波を含む。 In the present specification, "sound wave" refers to an elastic wave propagating in the air, and includes ultrasonic waves having a frequency higher than the human audible frequency (about 20 Hz to 20 kHz).
　典型的には、ハウジングの「第１壁部」は上壁、「第２壁部」は底壁を指すが、これに限られるものではない。 Typically, the "first wall" of the housing refers to the upper wall and the "second wall" refers to the bottom wall, but it is not limited to this.
　振動部材保持部が「側壁部と一体の構成要素からな」るとは、振動部材保持部の構成要素が上記側壁部と直接連なっている場合に限られず、例えば、振動部材保持部の構成要素が第２壁部に連なり、上記第２壁部を介して上記側壁部と一体になっていてもよい、ことを意味する。 The phrase "the vibrating member holding portion is composed of a component integrated with the side wall portion" is not limited to the case where the component of the vibrating member holding portion is directly connected to the side wall portion, for example, the component of the vibrating member holding portion. Means that may be connected to the second wall portion and may be integrated with the side wall portion via the second wall portion.
　上記側壁部の「内面」とは、上記側壁部の両面のうち、上記ハウジングの内部（収容空間）の側の面を指す。また、「側壁部の内面に沿った一方向」とは、例えば、上記第１壁部から上記第２壁部へ向かう方向を指す。ただし、その方向に限られるものではなく、例えば、上記第１壁部または上記第２壁部と平行な方向などであってもよい。 The "inner surface" of the side wall portion refers to the surface of both sides of the side wall portion on the side of the inside (accommodation space) of the housing. Further, "one direction along the inner surface of the side wall portion" refers to, for example, a direction from the first wall portion to the second wall portion. However, the direction is not limited to that, and may be, for example, a direction parallel to the first wall portion or the second wall portion.
　また、振動部材保持部に振動部材が「圧入され」るとは、上記振動部材保持部の隙間の寸法よりも上記振動部材の対応する寸法（厚さ）が若干量（これを「圧入しろ」と呼ぶ。）だけ大きく設定されている結果、上記振動部材保持部に上記振動部材が一方向から挿入されるとき、圧力をかけて挿入されることを意味する。この圧入自体によって、上記振動部材保持部に上記振動部材が保持された状態になる。 Further, when the vibrating member is "press-fitted" into the vibrating member holding portion, the corresponding dimension (thickness) of the vibrating member is slightly larger than the dimension of the gap of the vibrating member holding portion (this is "press-fitted"". As a result of being set as large as (referred to as), it means that when the vibrating member is inserted into the vibrating member holding portion from one direction, pressure is applied to the vibrating member. By this press-fitting itself, the vibrating member is held in the vibrating member holding portion.
　この開示の生体情報測定装置では、上記ハウジングは、面状に延在する第１壁部と、上記第１壁部に対向しかつ面状に延在する第２壁部と、上記第１壁部および上記第２壁部に交差して延在する側壁部とによって上記収容空間を画定している。上記側壁部の内側の特定の領域に、上記側壁部と一体の構成要素からなり、上記振動部材が上記側壁部の内面に沿った一方向から圧入され得る隙間をもつ振動部材保持部が設けられている。そして、上記振動部材保持部に、上記振動部材が上記一方向から圧入されて、上記振動部材の振動を上記側壁部に伝達させる態様で保持されている。したがって、上記振動部材が信号を受けて振動すると、上記側壁部が振動して、上記ハウジングの外部へ音波が発せられる。これにより、マイクロフォンを備えた外部端末と音波を介して通信が行われる。 In the biological information measuring device of the present disclosure, the housing has a first wall portion extending in a planar shape, a second wall portion facing the first wall portion and extending in a planar shape, and the first wall portion. The accommodation space is defined by a portion and a side wall portion extending so as to intersect the second wall portion. A vibrating member holding portion is provided in a specific region inside the side wall portion, which is composed of a component integrated with the side wall portion and has a gap through which the vibrating member can be press-fitted from one direction along the inner surface of the side wall portion. ing. Then, the vibrating member is press-fitted into the vibrating member holding portion from the one direction, and is held in such a manner that the vibration of the vibrating member is transmitted to the side wall portion. Therefore, when the vibrating member receives a signal and vibrates, the side wall portion vibrates and a sound wave is emitted to the outside of the housing. As a result, communication is performed with an external terminal equipped with a microphone via sound waves.
　典型的な使用態様として、上記ハウジングが卓上に置かれる場合、例えば、表示器、操作スイッチなどが配置された第１壁部が上壁としてユーザに面する一方、第２壁部は底壁としてテーブル等に面することが想定される。側壁部では、通常、配置されるべき部品が比較的少ないので、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。そのような状況下で、この生体情報測定装置によれば、上記側壁部の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。したがって、音波による通信状態を良好に保つことができる。 As a typical usage mode, when the housing is placed on a table, for example, the first wall portion on which an indicator, an operation switch, etc. are arranged faces the user as an upper wall, while the second wall portion serves as a bottom wall. It is expected to face a table or the like. Since there are usually relatively few components to be placed on the sidewalls, a relatively large area (area) can be reserved for vibration (and therefore sonic communication). Under such circumstances, according to this biological information measuring device, it is possible to vibrate a relatively wide area (area) of the side wall portion and emit sound waves to the outside. Therefore, it is possible to maintain a good communication state by sound waves.
　一実施形態の生体情報測定装置では、
　上記振動部材は、面状に延在する金属板と、この金属板の第一の面に固定された圧電素子層とを有する圧電ブザーであり、
　上記振動部材保持部は、上記構成要素として、上記側壁部の内面との間に上記隙間を画定する押さえリブを有し、
　上記振動部材保持部に上記圧電ブザーが圧入されるように、上記金属板の厚さよりも上記隙間が予め定められた圧入しろだけ小さく設定されている、ことを特徴とする。 In the biological information measuring device of one embodiment,
The vibrating member is a piezoelectric buzzer having a metal plate extending in a plane shape and a piezoelectric element layer fixed to the first surface of the metal plate.
The vibrating member holding portion has, as the component, a holding rib that defines the gap between the vibrating member holding portion and the inner surface of the side wall portion.
The gap is set smaller than the thickness of the metal plate by a predetermined press-fitting allowance so that the piezoelectric buzzer is press-fitted into the vibrating member holding portion.
　本明細書で、「圧電ブザー」とは、上記圧電素子層に上記信号としての電気信号を受けて、上記圧電素子層が振動を生ずるタイプの公知の部材である。 In the present specification, the "piezoelectric buzzer" is a known member of a type in which the piezoelectric element layer receives an electric signal as the signal and the piezoelectric element layer vibrates.
　金属板の「第一の面」（および、後述の「第二の面」）とは、面状に延在する板面を指す（つまり、端面ではない。）。 The "first surface" of the metal plate (and the "second surface" described later) refers to the plate surface extending in a plane shape (that is, not the end face).
　この一実施形態の生体情報測定装置では、上記振動部材は、面状に延在する金属板と、この金属板の第一の面に固定された圧電素子層とを有する圧電ブザーであり、実質的に板状の外形を有する。ここで、上記振動部材保持部は、上記構成要素として、上記側壁部の内面との間に上記隙間を画定する押さえリブを有し、上記振動部材保持部に上記圧電ブザーが圧入されるように、上記金属板の厚さよりも上記隙間が予め定められた圧入しろだけ小さく設定されている。言い換えれば、上記側壁部の内面と上記押さえリブとが画定する上記隙間に、上記圧入しろに対応して、上記金属板の端部（圧電素子層が固定されている部分以外の部分）が圧入されている。これにより、上記振動部材保持部に上記圧電ブザーが保持された状態になっている。この場合、上記圧電ブザーおよび上記押さえリブは、上記側壁部の内面に沿って配置され得るので、嵩張らず、装置の小型化に寄与する。 In the biological information measuring device of this embodiment, the vibrating member is a piezoelectric buzzer having a metal plate extending in a plane shape and a piezoelectric element layer fixed to the first surface of the metal plate, which is substantially the same. It has a plate-like outer shape. Here, the vibrating member holding portion has a holding rib that defines the gap between the vibrating member holding portion and the inner surface of the side wall portion as the component so that the piezoelectric buzzer is press-fitted into the vibrating member holding portion. The gap is set smaller than the thickness of the metal plate by a predetermined press-fitting margin. In other words, the end portion of the metal plate (the portion other than the portion where the piezoelectric element layer is fixed) is press-fitted into the gap defined by the inner surface of the side wall portion and the holding rib in accordance with the press-fitting margin. Has been done. As a result, the piezoelectric buzzer is held by the vibrating member holding portion. In this case, since the piezoelectric buzzer and the holding rib can be arranged along the inner surface of the side wall portion, they are not bulky and contribute to the miniaturization of the device.
　一実施形態の生体情報測定装置では、
　上記構成要素として、上記側壁部の内面に沿って上記圧電ブザーが保持された領域の、少なくとも上記一方向に垂直な方向に関して両側に、上記押さえリブが一対配置され、
　上記一対の押さえリブは、上記圧電ブザーをなす上記金属板の対応する端部を、それぞれ上記側壁部の内面へ向けて押圧する、
ことを特徴とする生体情報測定装置。 In the biological information measuring device of one embodiment,
As the component, a pair of holding ribs are arranged on both sides of the region where the piezoelectric buzzer is held along the inner surface of the side wall portion at least in a direction perpendicular to one direction.
The pair of pressing ribs press the corresponding ends of the metal plate forming the piezoelectric buzzer toward the inner surface of the side wall, respectively.
A biological information measuring device characterized by this.
　この一実施形態の生体情報測定装置では、上記構成要素として、上記側壁部の内面に沿って上記圧電ブザーが保持された領域の、少なくとも上記一方向に垂直な方向に関して両側に、上記押さえリブが一対配置されている。したがって、この生体情報測定装置の組み立て時に、上記側壁部の内面に沿った上記一方向から、上記側壁部の内面と上記一対の押さえリブとが画定する上記隙間に、上記一対の押さえリブによって遮られることなく、上記金属板の上記端部をスライドして圧入することができる。上記圧電ブザー（上記金属板）が圧入された状態で、上記一対の押さえリブは、上記金属板の対応する端部を、それぞれ上記側壁部の内面へ向けて押圧する。したがって、仮に上記振動部材保持部から上記圧電ブザーが離脱する向きの力が加わったとしても、上記金属板と上記側壁部の内面との間に摩擦力が生じて、上記振動部材保持部から上記圧電ブザーが離脱するのは抑制される。つまり、上記振動部材保持部に上記圧電ブザーが保持された状態となる。また、上記圧電ブザー（金属板）が上記側壁部の内面へ向けて押圧されるので、上記圧電ブザーから上記側壁部の内面への振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the biometric information measuring device of this embodiment, as the component, the holding ribs are provided on both sides of the region where the piezoelectric buzzer is held along the inner surface of the side wall portion at least in the direction perpendicular to one direction. A pair is arranged. Therefore, at the time of assembling this biological information measuring device, the pair of pressing ribs shield the gap defined by the inner surface of the side wall portion and the pair of pressing ribs from the one direction along the inner surface of the side wall portion. The end portion of the metal plate can be slid and press-fitted without being damaged. With the piezoelectric buzzer (the metal plate) press-fitted, the pair of pressing ribs press the corresponding ends of the metal plate toward the inner surface of the side wall, respectively. Therefore, even if a force is applied in the direction in which the piezoelectric buzzer is separated from the vibrating member holding portion, a frictional force is generated between the metal plate and the inner surface of the side wall portion, and the vibrating member holding portion is described as described above. The release of the piezoelectric buzzer is suppressed. That is, the piezoelectric buzzer is held by the vibrating member holding portion. Further, since the piezoelectric buzzer (metal plate) is pressed toward the inner surface of the side wall portion, the transmission efficiency of vibration from the piezoelectric buzzer to the inner surface of the side wall portion is increased, and the communication state by sound waves is further improved. Can be kept.

　上記圧電ブザーは、上記金属板の上記第一の面とは反対側の第二の面が、上記側壁部の内面に面しており、
　上記金属板の上記第二の面が上記側壁部の内面に接触するように、上記金属板の上記第二の面に向けて上記側壁部の一部が凹んだ形状を有している、
ことを特徴とする。 In the biological information measuring device of one embodiment,
In the piezoelectric buzzer, the second surface of the metal plate opposite to the first surface faces the inner surface of the side wall portion.
A part of the side wall portion is recessed toward the second surface of the metal plate so that the second surface of the metal plate comes into contact with the inner surface of the side wall portion.
It is characterized by that.
　この一実施形態の生体情報測定装置では、上記圧電ブザーは、上記金属板の上記第一の面とは反対側の第二の面が、上記側壁部の内面に面している。また、上記金属板の上記第二の面に向けて上記側壁部の一部が凹んだ形状を有することによって、上記金属板の上記第二の面が上記側壁部の内面に接触している。したがって、上記圧電ブザーの振動が上記ハウジングの上記側壁部に直接的に伝達される。この結果、振動の伝達効率が高まって、音波による通信状態を良好に保つことができる。 In the biometric information measuring device of this embodiment, in the piezoelectric buzzer, the second surface of the metal plate opposite to the first surface faces the inner surface of the side wall portion. Further, since a part of the side wall portion is recessed toward the second surface of the metal plate, the second surface of the metal plate is in contact with the inner surface of the side wall portion. Therefore, the vibration of the piezoelectric buzzer is directly transmitted to the side wall portion of the housing. As a result, the transmission efficiency of vibration is increased, and the communication state by sound waves can be kept good.
　また、実質的に板状の外形を有する上記圧電ブザーの上記圧電素子層が設けられている側では、大部分の領域（上記金属板の端部以外の領域）が、上記一対の押さえリブに覆われることなく、開放され得る。その場合、上記振動部材保持部（上記一対の押さえリブを含む）によって干渉されることなく、例えば上記収容空間の内部に配置された制御部から配線を介して、上記圧電素子層に対して上記信号としての電気信号を供給することができる。 Further, on the side of the piezoelectric buzzer having a substantially plate-like outer shape on which the piezoelectric element layer is provided, most of the region (the region other than the end of the metal plate) is formed into the pair of holding ribs. It can be opened without being covered. In that case, without being interfered by the vibrating member holding portion (including the pair of pressing ribs), for example, from the control unit arranged inside the accommodation space via wiring, the piezoelectric element layer is described. An electrical signal as a signal can be supplied.
　一実施形態の生体情報測定装置では、上記側壁部の内面のうち上記金属板の上記第二の面に接する領域は、上記圧電ブザーが圧入された状態で上記金属板の上記第二の面と平行面となるように形成されている、ことを特徴とする。 In the biological information measuring device of one embodiment, the region of the inner surface of the side wall portion in contact with the second surface of the metal plate is the second surface of the metal plate with the piezoelectric buzzer press-fitted. It is characterized in that it is formed so as to be parallel planes.
　この一実施形態の生体情報測定装置では、上記圧電ブザーが圧入された状態で、上記金属板の上記第二の面と、上記側壁部の内面のうち上記接する領域とが、平行面となって面接触している。この結果、振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the biometric information measuring device of this embodiment, in a state where the piezoelectric buzzer is press-fitted, the second surface of the metal plate and the contacting region of the inner surface of the side wall portion become parallel surfaces. There is surface contact. As a result, the transmission efficiency of vibration is increased, and the communication state by sound waves can be maintained even better.

　上記第１壁部に、この第１壁部が上記側壁部に対して装着された状態で、上記振動部材保持部に保持された上記圧電ブザーを、上記側壁部の内面へ向けて付勢する弾性突起が設けられている、ことを特徴とする。 In the biological information measuring device of one embodiment,
The first wall portion is configured to be removable from the side wall portion.
With the first wall portion mounted on the first wall portion with respect to the side wall portion, the piezoelectric buzzer held by the vibrating member holding portion is urged toward the inner surface of the side wall portion. It is characterized in that it is provided with elastic protrusions.
　本明細書で、上記第１壁部は、上記側壁部に対して「着脱可能」とは、典型的には、上記側壁部に対して、上記第２壁部へ向って装着され得、また、その逆に、上記側壁部に対して、上記第２壁部から遠ざかる向きに取り外され得ることを指す。 In the present specification, the first wall portion is "detachable" with respect to the side wall portion, and can be typically mounted on the side wall portion toward the second wall portion. On the contrary, it means that the side wall portion can be removed in a direction away from the second wall portion.
　この一実施形態の生体情報測定装置では、上記振動部材保持部に上記圧電ブザーが保持され、かつ、上記第１壁部が上記側壁部に対して装着された状態で、上記第１壁部の弾性突起から上記圧電ブザーが上記側壁部の内面へ向けて付勢され、押し付けられる。したがって、上記圧電ブザーから上記側壁部の内面への振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the biological information measuring device of this embodiment, the piezoelectric buzzer is held by the vibrating member holding portion, and the first wall portion is attached to the side wall portion of the first wall portion. The piezoelectric buzzer is urged and pressed from the elastic protrusion toward the inner surface of the side wall portion. Therefore, the efficiency of transmitting vibration from the piezoelectric buzzer to the inner surface of the side wall portion is increased, and the communication state by sound waves can be maintained even better.

As a result, the piezoelectric buzzer can be vibrated. Further, the first electrode terminal and the second electrode terminal each have elasticity, come into contact with the piezoelectric buzzer, and urge the side wall portion toward the inner surface. As a result, the piezoelectric buzzer is pressed against the inner surface of the side wall portion.

　この開示の血圧計では、上記生体情報測定装置を備えているので、マイクロフォンを備えた外部端末と音波を介して通信を行うことができる。また、この血圧計では、上記収容空間の内部に、被測定部位を圧迫するための流体を供給するポンプを有し、上記ポンプからの流体をハウジング外部へ供給するためのエアチューブ接続口が、上記収容空間の四方位のうち一方位を画定する第１側壁部に設けられている。このため、仮に上記第１側壁部の内面に上記振動部材保持部を設け、上記振動部材保持部に保持された状態の上記振動部材（または圧電ブザー）によって上記第１側壁部を振動させる構成にすると、振動の伝達状態（つまり、通信状態）が悪くなる可能性がある。そこで、この血圧計では、上記振動部材を保持した状態の上記振動部材保持部が、上記収容空間の四方位のうち上記一方位とは異なる他の方位を画定する上記第２側壁部の内側に設けられている。上記第２側壁部では、上記エアチューブ接続口その他の血圧計の構成部品を配置しないことによって、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。そのような状況下で、この血圧計によれば、上記第２側壁部の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。したがって、音波による通信状態を良好に保つことができる。 Since the blood pressure monitor of this disclosure is equipped with the above-mentioned biometric information measuring device, it is possible to communicate with an external terminal equipped with a microphone via sound waves. Further, in this sphygmomanometer, a pump for supplying a fluid for compressing the measurement site is provided inside the accommodation space, and an air tube connection port for supplying the fluid from the pump to the outside of the housing is provided. It is provided on the first side wall portion that defines one of the four directions of the accommodation space. Therefore, the vibrating member holding portion is temporarily provided on the inner surface of the first side wall portion, and the first side wall portion is vibrated by the vibrating member (or piezoelectric buzzer) held by the vibrating member holding portion. Then, the vibration transmission state (that is, the communication state) may be deteriorated. Therefore, in this sphygmomanometer, the vibrating member holding portion in a state of holding the vibrating member is inside the second side wall portion that defines another direction different from the one position among the four directions of the accommodation space. It is provided. By not arranging the air tube connection port and other components of the sphygmomanometer in the second side wall portion, a relatively large area (area) can be secured for vibration (and therefore sound wave communication). Under such circumstances, according to this sphygmomanometer, a relatively wide area (area) of the second side wall portion can be vibrated to emit sound waves to the outside. Therefore, it is possible to maintain a good communication state by sound waves.
　以上より明らかなように、この開示の生体情報測定装置および血圧計によれば、ハウジングをなす側壁部の内面に振動部材を固定して側壁部を振動させることにより、音波による通信状態を良好に保つことができる。 As is clear from the above, according to the biological information measuring device and the sphygmomanometer of the present disclosure, by fixing the vibrating member to the inner surface of the side wall portion forming the housing and vibrating the side wall portion, the communication state by sound waves is improved. Can be kept.

　以下、この発明の実施の形態を、図面を参照しながら詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
　図１は、この発明の生体情報測定装置の一実施形態としての卓上式血圧計１の外観を示している。図２は、血圧計１の外観を、図１におけるのとは略反対方向から見たところを示している。この血圧計１は、テーブル５００（図１参照）等の水平面上に載置され、マイクロフォンを備えた外部端末（図示せず）と音波（超音波を含む。）を介して通信を行う仕様になっている。 FIG. 1 shows the appearance of the desktop sphygmomanometer 1 as an embodiment of the biological information measuring device of the present invention. FIG. 2 shows the appearance of the sphygmomanometer 1 as viewed from a direction substantially opposite to that in FIG. The sphygmomanometer 1 is placed on a horizontal surface such as a table 500 (see FIG. 1) and communicates with an external terminal (not shown) equipped with a microphone via sound waves (including ultrasonic waves). It has become.
　図１、図２によって分かるように、血圧計１の筐体であるハウジング１０は、正面パネルをなすように面状に延在する第１壁部としての上壁（上ハウジング）１１と、上壁１１に対向しかつ面状に延在する第２壁部としての底壁１２と、上壁１１および底壁１２に交差して延在する側壁部１３Ｓとを備えている。これらの上壁１１と底壁１２と側壁部１３Ｓとによって、図３に示すように、ハウジング１０の内部に収容空間４００を画定している。側壁部１３Ｓは、収容空間４００の四方位（前後左右の方位）をそれぞれ画定する前側壁１４、後側壁１７、左側壁１５、右側壁１６を有している。この例では、底壁１２と側壁部１３Ｓとは、合成樹脂の一体成形により、下ハウジング１３として一体に構成されている。上壁１１は、下ハウジング１３とは別体として構成され、下ハウジング１３（特に、側壁部１３Ｓ）に対して着脱可能になっている。 As can be seen from FIGS. 1 and 2, the housing 10 which is the housing of the sphygmomanometer 1 has an upper wall (upper housing) 11 as a first wall portion extending in a plane so as to form a front panel, and an upper wall (upper housing) 11. It includes a bottom wall 12 as a second wall portion that faces the wall 11 and extends in a plane shape, and a side wall portion 13S that intersects the upper wall 11 and the bottom wall 12 and extends. As shown in FIG. 3, the accommodation space 400 is defined inside the housing 10 by the upper wall 11, the bottom wall 12, and the side wall portion 13S. The side wall portion 13S has a front side wall 14, a rear side wall 17, a left side wall 15, and a right side wall 16 that define four directions (front-back, left-right directions) of the accommodation space 400, respectively. In this example, the bottom wall 12 and the side wall portion 13S are integrally formed as the lower housing 13 by integrally molding a synthetic resin. The upper wall 11 is configured as a separate body from the lower housing 13, and is removable from the lower housing 13 (particularly, the side wall portion 13S).
　図１、図２によって分かるように、この例では、上壁１１は、前方から後方に向かうにつれて次第に高くなるように水平面に対して約２５°傾斜して延在する傾斜面になっている。底壁１２は、概ね平坦面になっているが、底壁１２の後縁部１２Ｂは、前方から後方に向かうにつれて次第に高くなるように水平面に対して約２５°傾斜した傾斜面になっている。前側壁１４と後側壁１７は、下から上に向かうにつれて次第に前になるように鉛直面に対してそれぞれ約３０°、約２０°傾斜した傾斜面になっている。左側壁１５、右側壁１６は、それぞれ下から上に向かうにつれて略鉛直に立ち上がる鉛直面になっている。 As can be seen from FIGS. 1 and 2, in this example, the upper wall 11 is an inclined surface extending at an inclination of about 25 ° with respect to the horizontal plane so as to gradually increase from the front to the rear. The bottom wall 12 has a substantially flat surface, but the trailing edge portion 12B of the bottom wall 12 has an inclined surface inclined by about 25 ° with respect to the horizontal plane so as to gradually increase from the front to the rear. .. The front side wall 14 and the rear side wall 17 are inclined surfaces that are inclined by about 30 ° and about 20 ° with respect to the vertical plane so as to gradually move forward from the bottom to the top. The left side wall 15 and the right side wall 16 are vertically facing each other so as to rise substantially vertically from the bottom to the top.
　図１に示すように、この例では、上壁１１には、ユーザが血圧計１に指示を入力するための操作部５２と、血圧に関する情報を表示する表示器５０とが設けられている。操作部５２は、ユーザが血圧測定のオンオフを指示するための測定／停止スイッチ５２Ａと、血圧計１の記憶部（図示しないが、収容空間４００内に配置されている）に記憶されている過去の血圧測定結果を呼び出すためのメモリスイッチ５２Ｂとを含んでいる。表示器５０は、血圧に関する情報として、最高血圧、最低血圧、脈拍数などを表示する。 As shown in FIG. 1, in this example, the upper wall 11 is provided with an operation unit 52 for the user to input an instruction to the sphygmomanometer 1 and a display 50 for displaying information on blood pressure. The operation unit 52 has a measurement / stop switch 52A for instructing the user to turn on / off the blood pressure measurement, and a past stored in a storage unit (not shown, but arranged in the accommodation space 400) of the sphygmomanometer 1. It includes a memory switch 52B for recalling the blood pressure measurement result of the above. The display 50 displays the systolic blood pressure, the diastolic blood pressure, the pulse rate, and the like as information on the blood pressure.
　また、この例では、第１側壁部としての左側壁１５に、エアチューブ接続口としてのエアコネクタ３９と、このエアコネクタ３９に取り付けられたエアプラグ３８とが配置されている。これらのエアコネクタ３９とエアプラグ３８とを介して、収容空間４００内部に配置されたポンプ（図示せず）からの空気（流体）がハウジング１０の外部、この例では図示しない血圧測定用カフへ供給される。これにより、血圧測定用カフによって被測定部位（例えば、上腕）が圧迫され、血圧測定が行われる。 Further, in this example, the air connector 39 as the air tube connection port and the air plug 38 attached to the air connector 39 are arranged on the left side wall 15 as the first side wall portion. Through these air connectors 39 and air plugs 38, air (fluid) from a pump (not shown) arranged inside the accommodation space 400 is supplied to the outside of the housing 10, a blood pressure measuring cuff (not shown in this example). Will be done. As a result, the blood pressure measurement cuff presses the area to be measured (for example, the upper arm), and the blood pressure is measured.
　図２に示すように、この例では、後側壁１７に、ＤＣジャック５３が配置されている。このＤＣジャック５３には、ハウジング１０の外部からＤＣ電圧（例えば、ＤＣ６Ｖ）が供給される。 As shown in FIG. 2, in this example, the DC jack 53 is arranged on the rear side wall 17. A DC voltage (for example, DC6V) is supplied to the DC jack 53 from the outside of the housing 10.
　また、この例では、底壁１２において、略中央に略矩形の電池蓋１４０が設けられ、また、四隅に短円柱状のゴム脚１８１，１８２，１８３，１８４が設けられている。ハウジング１０から電池蓋１４０が取り外された状態で、収容空間４００内に配置された電池収容部（図示せず）へ外部から電池を入れたり、逆に出したりすることが可能になっている。ハウジング１０に電池蓋１４０が取り付けられた状態では、電池蓋１４０はフック１４１で底壁１２に係合して、電池収容部に収容された電池がハウジング１０から脱落するのを防止する。ゴム脚１８１，１８２，１８３，１８４は、ハウジング１０がテーブル５００等の水平面上に置かれたとき、ハウジング１０の姿勢を維持する。 Further, in this example, in the bottom wall 12, a substantially rectangular battery lid 140 is provided in the substantially center, and short columnar rubber legs 181, 182, 183, 184 are provided at the four corners. With the battery cover 140 removed from the housing 10, it is possible to insert and remove the battery from the outside into the battery accommodating portion (not shown) arranged in the accommodating space 400. When the battery lid 140 is attached to the housing 10, the battery lid 140 engages with the bottom wall 12 with the hook 141 to prevent the battery housed in the battery housing from falling out of the housing 10. The rubber legs 181, 182, 183, 184 maintain the posture of the housing 10 when the housing 10 is placed on a horizontal surface such as a table 500.
　分かるように、この例では、ハウジング１０の前側壁１４と右側壁１６には、血圧測定のための本来の構成部品が配置されていない。前側壁１４よりも右側壁１６の方が広い面積を占めているので、右側壁１６を用いれば、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。 As can be seen, in this example, the original components for blood pressure measurement are not arranged on the front side wall 14 and the right side wall 16 of the housing 10. Since the right side wall 16 occupies a larger area than the front side wall 14, a relatively large area (area) can be reserved for vibration (and therefore sound wave communication) by using the right side wall 16.
　（実施例１）
　そこで、この例では、図３に示すように、第２側壁部としての右側壁１６の内面１６ｉに振動部材保持部７０が設けられ、この振動部材保持部７０に、振動部材としての圧電ブザー４０が保持されている。右側壁１６の内面１６ｉとは、右側壁１６の両面（内面１６ｉと外面１６ｏ）のうち、ハウジング１０の内部（収容空間４００）の側に向いた面を指す。圧電ブザー４０は、振動部材保持部７０に、発生した振動を右側壁１６に伝達させる態様で固定されている。 (Example 1)
Therefore, in this example, as shown in FIG. 3, a vibrating member holding portion 70 is provided on the inner surface 16i of the right side wall 16 as the second side wall portion, and the vibrating member holding portion 70 is provided with a piezoelectric buzzer 40 as a vibrating member. Is held. The inner surface 16i of the right side wall 16 refers to a surface of both surfaces (inner surface 16i and outer surface 16o) of the right side wall 16 facing the inside (accommodation space 400) of the housing 10. The piezoelectric buzzer 40 is fixed to the vibrating member holding portion 70 in such a manner that the generated vibration is transmitted to the right side wall 16.
　具体的には、図４（Ａ）と図４（Ｂ）は、図３における振動部材保持部７０の近傍（破線１６ｘで示す領域）を拡大して、互いに別の方向から見たところを示している。これらの図では、いずれも、振動部材保持部７０に、圧電ブザー４０が圧入されて保持された状態にある。 Specifically, FIGS. 4 (A) and 4 (B) show an enlarged view of the vicinity of the vibrating member holding portion 70 (the region shown by the broken line 16x) in FIG. 3 and viewed from different directions. ing. In each of these figures, the piezoelectric buzzer 40 is press-fitted and held in the vibrating member holding portion 70.
　図５に示すように、図３における振動部材保持部７０から、振動部材としての圧電ブザー４０が、矢印Ａ２で示す斜め上方へスライドして取り外され得る。逆に、振動部材保持部７０に、圧電ブザー４０が、一方向としての矢印Ａ１で示す斜め下方へスライド挿入（圧入）して固定され得る。矢印Ａ１，Ａ２で示す方向は、いずれも右側壁１６の上縁１６ｅに対して垂直で、かつ右側壁１６の内面１６ｉに沿った方向に相当する。 As shown in FIG. 5, the piezoelectric buzzer 40 as the vibrating member can be removed from the vibrating member holding portion 70 in FIG. 3 by sliding diagonally upward as indicated by the arrow A2. On the contrary, the piezoelectric buzzer 40 can be fixed to the vibrating member holding portion 70 by slide-inserting (press-fitting) diagonally downward as indicated by the arrow A1 as one direction. The directions indicated by the arrows A1 and A2 are perpendicular to the upper edge 16e of the right side wall 16 and correspond to the direction along the inner surface 16i of the right side wall 16.
　図５中に示すように、圧電ブザー４０は、円形の面状に延在する金属板４１と、この金属板４１の第一の面４１ａに固定された円形の圧電素子層４２とを備えている。金属板４１の第一の面４１ａと反対側の第二の面４１ｂは平坦面になっている。これにより、圧電ブザー４０は、全体として実質的に板状の外形を有している。振動部材保持部７０に圧電ブザー４０が保持された状態では、第二の面４１ｂが右側壁１６の内面１６ｉ（特に、後述の領域１６ｉｘ）に向けられるようになっている。この例では、圧電ブザー４０（金属板４１）の外径Ｄは約１２ｍｍ、金属板４１の厚さは約０．４１ｍｍ±０．０３ｍｍに設定されている。この例では、圧電素子層４２の表面（図示しない金属層が設けられている）と、金属板４１の第一の面４１ａの周縁部（圧電素子層４２からはみ出した部分）とに、それぞれリード配線４３，４４が接続されている。収容空間４００の内部に設けられた制御部（図示せず）から、これらのリード配線４３，４４を通して、圧電素子層４２を振動させる信号としての電気信号が供給される。この例では、圧電ブザー４０は約２０ｋＨｚの周波数で振動する。このような圧電ブザー４０は、公知の部材である。 As shown in FIG. 5, the piezoelectric buzzer 40 includes a metal plate 41 extending in a circular surface shape and a circular piezoelectric element layer 42 fixed to the first surface 41a of the metal plate 41. There is. The second surface 41b opposite to the first surface 41a of the metal plate 41 is a flat surface. As a result, the piezoelectric buzzer 40 has a substantially plate-like outer shape as a whole. When the piezoelectric buzzer 40 is held by the vibrating member holding portion 70, the second surface 41b is directed toward the inner surface 16i (particularly, the region 16ix described later) of the right side wall 16. In this example, the outer diameter D of the piezoelectric buzzer 40 (metal plate 41) is set to about 12 mm, and the thickness of the metal plate 41 is set to about 0.41 mm ± 0.03 mm. In this example, leads are provided on the surface of the piezoelectric element layer 42 (a metal layer (not shown) is provided) and on the peripheral edge of the first surface 41a of the metal plate 41 (a portion protruding from the piezoelectric element layer 42). Wiring 43 and 44 are connected. An electric signal as a signal for vibrating the piezoelectric element layer 42 is supplied from a control unit (not shown) provided inside the accommodation space 400 through these lead wirings 43 and 44. In this example, the piezoelectric buzzer 40 vibrates at a frequency of about 20 kHz. Such a piezoelectric buzzer 40 is a known member.
　図４（Ａ）、図４（Ｂ）によって分かるように、この例では、圧電ブザー４０の金属板４１の第二の面４１ｂが右側壁１６の内面１６ｉに接触するように、金属板４１の第二の面４１ｂに向けて、右側壁１６の一部１６ｂｘが凹んだ形状を有している。この凹みは、上記一方向（図５中に矢印Ａ１で示すスライド挿入方向）に沿って延在するストライプ状に形成されている。これに伴って、収容空間４００の内部へ向けて、より詳しくは、圧電ブザー４０の金属板４１の第二の面４１ｂに向けて、右側壁１６の内面１６ｉの一部（領域）１６ｉｘがストライプ状に突出した形状を有している。ストライプ状の領域１６ｉｘは、圧電ブザー４０が圧入された状態で金属板４１の第二の面４１ｂと平行面となって、面接触するように形成されている。ストライプ状の領域１６ｉｘの左右両側には、それぞれ、その領域１６ｉｘに対して相対的に凹んだストライプ状の空間１６ｉｃ，１６ｉｄが形成されている。 As can be seen from FIGS. 4A and 4B, in this example, the metal plate 41 of the piezoelectric buzzer 40 is contacted with the inner surface 16i of the right side wall 16 so that the second surface 41b of the metal plate 41 is in contact with the inner surface 16i of the right side wall 16. A part 16bx of the right side wall 16 has a concave shape toward the second surface 41b. This recess is formed in a striped shape extending along the above-mentioned one direction (the slide insertion direction indicated by the arrow A1 in FIG. 5). Along with this, a part (region) 16ix of the inner surface 16i of the right side wall 16 is striped toward the inside of the accommodation space 400, more specifically, toward the second surface 41b of the metal plate 41 of the piezoelectric buzzer 40. It has a protruding shape. The striped region 16ix is formed so as to be in surface contact with the second surface 41b of the metal plate 41 in a state where the piezoelectric buzzer 40 is press-fitted. Striped spaces 16ic and 16id are formed on the left and right sides of the striped region 16ix, respectively, which are recessed relative to the striped region 16ix.
　図６（Ａ）、図６（Ｂ）は、圧電ブザー４０が取り外された状態の振動部材保持部７０の近傍を、それぞれ図４（Ａ）、図４（Ｂ）に対応して互いに別の方向から見たところを示している。この例では、振動部材保持部７０は、ハウジング１０（特に、右側壁１６）と一体の構成要素からなっている。具体的には、振動部材保持部７０は、上記一方向（図５中に矢印Ａ１で示すスライド挿入方向）に垂直な方向に関して両側（すなわち図６（Ａ）、図６（Ｂ）において左右）に配置された一対の押さえリブ７１，７２と、スライド挿入の終端を画定するストッパを兼ねた押さえリブ７３とを有している。 6 (A) and 6 (B) show that the vicinity of the vibrating member holding portion 70 in the state where the piezoelectric buzzer 40 is removed is different from each other corresponding to FIGS. 4 (A) and 4 (B), respectively. It shows the view from the direction. In this example, the vibrating member holding portion 70 is an integral component of the housing 10 (particularly, the right side wall 16). Specifically, the vibrating member holding portion 70 is provided on both sides (that is, left and right in FIGS. 6A and 6B) with respect to a direction perpendicular to the one direction (slide insertion direction indicated by arrow A1 in FIG. 5). It has a pair of holding ribs 71 and 72 arranged in the above, and a holding rib 73 that also serves as a stopper that defines the end of the slide insertion.
　押さえリブ７１，７２は、互いに左右対称な略コの字状の断面を有して、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って延在している。押さえリブ７１，７２の上記スライド挿入方向に沿った高さは、概ね、圧電ブザー４０の上縁に達するレベルにある。押さえリブ７１，７２のうち右側壁１６の内面１６ｉに面した対向部分（コの字の端辺に相当する部分）７１Ａ，７２Ａの下部は、それぞれ右側壁１６と連なり一体に構成されている。それらの対向部分７１Ａ，７２Ａの上部は、それぞれ右側壁１６の内面１６ｉ（特に、領域１６ｉｘ）との間に隙間ｄ１，ｄ２を有している。また、押さえリブ７３は、左右方向に関して一対の押さえリブ７１，７２の間（中央）に配置され、略Ｔ字状の断面を有して、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って延在している。押さえリブ７３の上記スライド挿入方向に沿った高さは、概ね、圧電ブザー４０の周縁部（ここでは、圧電素子層４２からはみ出した下端部）に留まるレベルにある。押さえリブ７３のうち右側壁１６の内面１６ｉに面した対向部分（Ｔの字のベースラインに相当する部分）７３Ｂの下部は、右側壁１６と連なり一体に構成されている。その対向部分７３Ｂの上部は、右側壁１６の内面１６ｉ（特に、領域１６ｉｘ）との間に隙間ｄ３を有している。 The pressing ribs 71 and 72 have a substantially U-shaped cross section that is symmetrical to each other, and extend along the slide insertion direction (indicated by arrow A1 in FIG. 5). The height of the pressing ribs 71 and 72 along the slide insertion direction is approximately at a level reaching the upper edge of the piezoelectric buzzer 40. Of the pressing ribs 71 and 72, the lower portions of the facing portions (the portions corresponding to the U-shaped ends) 71A and 72A facing the inner surface 16i of the right side wall 16 are connected to and integrally formed with the right side wall 16, respectively. The upper portions of the facing portions 71A and 72A each have gaps d1 and d2 between the right side wall 16 and the inner surface 16i (particularly, the region 16ix). Further, the pressing rib 73 is arranged between the pair of pressing ribs 71 and 72 (center) in the left-right direction, has a substantially T-shaped cross section, and is indicated by an arrow A1 in the slide insertion direction (in FIG. 5). ) Extends along. The height of the pressing rib 73 along the slide insertion direction is generally at a level of staying at the peripheral edge portion of the piezoelectric buzzer 40 (here, the lower end portion protruding from the piezoelectric element layer 42). The lower portion of the pressing rib 73 facing the inner surface 16i of the right side wall 16 (the part corresponding to the T-shaped baseline) 73B is integrally formed with the right side wall 16. The upper portion of the facing portion 73B has a gap d3 with the inner surface 16i (particularly, the region 16ix) of the right side wall 16.
　図７は、圧電ブザー４０が取り外された状態（図６（Ａ）、図６（Ｂ）に示した状態）の振動部材保持部７０を、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って上方から見たところを示している。なお、簡単のため、図７（および後述の図１０）において、上下は、上記スライド挿入方向に沿った上下を指すものとする。 FIG. 7 shows the vibrating member holding portion 70 in the state where the piezoelectric buzzer 40 is removed (the state shown in FIGS. 6A and 6B) in the slide insertion direction (arrow A1 in FIG. 5). ) Is shown from above. For the sake of simplicity, in FIG. 7 (and FIG. 10 described later), the top and bottom refer to the top and bottom along the slide insertion direction.
　図７によって分かるように、押さえリブ７１の対向部分７１Ａは、右側壁１６の内面１６ｉとの間に、平坦な上面７１ａ０のレベル（高さ）から、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面７１ａ１と、この案内面７１ａ１の下端から下方に延在する押圧面７１ｂとを有している。この押圧面７１ｂは、振動部材保持部７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した左端部）に対向する。押圧面７１ｂは、右側壁１６の内面１６ｉのストライプ状の領域１６ｉｘとの間に、その領域１６ｉｘに対して垂直な方向の隙間ｄ１を形成している。案内面７１ａ１は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ１に入るように案内する。対向部分７１Ａは、さらに、押圧面７１ｂの下部レベルにある平坦面７１ｃと、この平坦面７１ｃのレベルから、右へ進むに伴って次第に高さが低くなるように傾斜した規制面７１ｄとを有している（図８（Ａ）参照）。この規制面７１ｄは、圧電ブザー４０が左方向へ位置ずれするのを規制する。 As can be seen from FIG. 7, the height of the facing portion 71A of the pressing rib 71 gradually increases from the level (height) of the flat upper surface 71a0 to the inner surface 16i of the right side wall 16 as it approaches the inner surface 16i. It has a guide surface 71a1 inclined so as to be low, and a pressing surface 71b extending downward from the lower end of the guide surface 71a1. The pressing surface 71b faces the peripheral edge of the metal plate 41 (here, the left end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 70. The pressing surface 71b forms a gap d1 in the direction perpendicular to the region 16ix between the pressing surface 71b and the striped region 16ix of the inner surface 16i of the right side wall 16. When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surface 71a1 guides the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d1. The facing portion 71A further has a flat surface 71c at the lower level of the pressing surface 71b, and a regulation surface 71d inclined so that the height gradually decreases as the flat surface 71c moves to the right. (See FIG. 8 (A)). The regulation surface 71d regulates the piezoelectric buzzer 40 from being displaced to the left.
　同様に、図７中に示す押さえリブ７２の対向部分７２Ａも、右側壁１６の内面１６ｉとの間に、平坦な上面７２ａ０のレベルから、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面７２ａ１と、この案内面７２ａ１の下端から下方に延在する押圧面７２ｂとを有している。この押圧面７２ｂは、振動部材保持部７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した右端部）に対向する。押圧面７２ｂは、右側壁１６の内面１６ｉのストライプ状の領域１６ｉｘとの間に、その領域１６ｉｘに対して垂直な方向の隙間ｄ２を形成している。案内面７２ａ１は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ２に入るように案内する。さらに、対向部分７２Ａは、押圧面７２ｂの下部レベルにある平坦面７２ｃと、この平坦面７２ｃのレベルから、左へ進むに伴って次第に高さが低くなるように傾斜した規制面７２ｄとを有している（図８（Ａ）参照）。この規制面７２ｄは、圧電ブザー４０が右方向へ位置ずれするのを規制する。 Similarly, the opposite portion 72A of the pressing rib 72 shown in FIG. 7 also gradually decreases in height from the level of the flat upper surface 72a0 to the inner surface 16i of the right side wall 16 as it approaches the inner surface 16i. It has a guide surface 72a1 inclined to the surface and a pressing surface 72b extending downward from the lower end of the guide surface 72a1. The pressing surface 72b faces the peripheral edge of the metal plate 41 (here, the right end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 70. The pressing surface 72b forms a gap d2 in the direction perpendicular to the region 16ix between the pressing surface 72b and the striped region 16ix of the inner surface 16i of the right side wall 16. When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surface 72a1 guides the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d2. Further, the facing portion 72A has a flat surface 72c at the lower level of the pressing surface 72b and a regulation surface 72d inclined so that the height gradually decreases as the flat surface 72c moves to the left. (See FIG. 8 (A)). The regulation surface 72d regulates the piezoelectric buzzer 40 from being displaced to the right.
　図７中に示す押さえリブ７３の対向部分７３Ｂは、右側壁１６の内面１６ｉとの間に、平坦な上面７３ｃ０のレベルから、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面７３ｃ１と、この案内面７３ｃ１の下端から下方に延在する押圧面７３ｃ２と、上記スライド挿入の終端を画定するストッパ面７３ｃ３とを有している。押圧面７３ｃ２は、振動部材保持部７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した下端部）に対向する。押圧面７３ｃ２は、右側壁１６の内面１６ｉのストライプ状の領域１６ｉｘとの間に、その領域１６ｉｘに対して垂直な方向の隙間ｄ３を形成している。案内面７３ｃ１は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ３に入るように案内する。ストッパ面７３ｃ３は、スライド挿入される圧電ブザー４０に当接して、圧電ブザー４０のスライド挿入を停止させる（図８（Ａ）参照）。 The facing portion 73B of the pressing rib 73 shown in FIG. 7 is inclined from the level of the flat upper surface 73c0 to the inner surface 16i of the right side wall 16 so as to gradually decrease in height as it approaches the inner surface 16i. It has a guide surface 73c1, a pressing surface 73c2 extending downward from the lower end of the guide surface 73c1, and a stopper surface 73c3 that defines the end of the slide insertion. The pressing surface 73c2 faces the peripheral edge portion of the metal plate 41 (here, the lower end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 70. The pressing surface 73c2 forms a gap d3 in the direction perpendicular to the region 16ix between the pressing surface 73c2 and the striped region 16ix of the inner surface 16i of the right side wall 16. When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surface 73c1 guides the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d3. The stopper surface 73c3 abuts on the piezoelectric buzzer 40 to be slide-inserted to stop the slide insertion of the piezoelectric buzzer 40 (see FIG. 8A).
　上述の隙間ｄ１，ｄ２，ｄ３の寸法は、スライド挿入（圧入）された圧電ブザー４０（金属板４１）を挟持できるように、金属板４１の厚さよりも若干だけ小さく、この例ではいずれも約０．３８ｍｍに設定されている。言い換えれば、振動部材保持部７０の隙間ｄ１，ｄ２，ｄ３の寸法よりも圧電ブザー４０の対応する寸法（厚さ）が若干量（これを「圧入しろ」と呼ぶ。）だけ大きく設定されている。この例では、圧入しろは、約０．０３ｍｍ±０．０３ｍｍに設定されている。 The dimensions of the gaps d1, d2, and d3 described above are slightly smaller than the thickness of the metal plate 41 so that the slide-inserted (press-fitted) piezoelectric buzzer 40 (metal plate 41) can be sandwiched. It is set to 0.38 mm. In other words, the corresponding dimension (thickness) of the piezoelectric buzzer 40 is set slightly larger than the dimension of the gaps d1, d2, d3 of the vibrating member holding portion 70 (this is called "press-fitting"). .. In this example, the press-fitting margin is set to about 0.03 mm ± 0.03 mm.
　血圧計１の組立過程では、図５中に矢印Ａ１で示すように、振動部材保持部７０に、圧電ブザー４０がスライド挿入される。すると、まず、図７中に示した案内面７１ａ１，７２ａ１が圧電ブザー４０の金属板４１を案内して、右側壁１６の内面１６ｉ（特に、領域１６ｉｘ）と押圧面７１ｂ，７２ｂとの間の隙間ｄ１，ｄ２に導く。さらに、圧電ブザー４０が圧力をかけて挿入されると、圧電ブザー４０の金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した左端部、右端部）が隙間ｄ１，ｄ２に圧入され、下方へスライドする。さらに、圧電ブザー４０が圧力をかけて挿入されると、押圧面７１ｂ，７２ｂの下部レベルにある規制面７１ｄ，７２ｄは、それぞれ圧電ブザー４０が左方向、右方向へ位置ずれするのを規制する（図８（Ａ）参照）。また、圧電ブザー４０の金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した下端部）が隙間ｄ３に圧入される。また、ストッパ面７３ｃ３が圧電ブザー４０の下方への動きを規制する。このとき、押圧面７１ｂ，７２ｂ，７３ｃ２が圧電ブザー４０の金属板４１の周縁部のうち押圧する範囲７１ｂ′，７２ｂ′，７３ｃ２′を、図８（Ａ）中に斜線で模式的に示している（なお、図８（Ｂ）は、圧電ブザー４０に対する振動部材保持部７０の構成要素の配置を、図７におけるのと同じ視方向で模式的に示している。）。このように、右側壁１６の内面１６ｉと押さえリブ７１，７２，７３とが画定する隙間ｄ１，ｄ２，ｄ３に、上述の圧入しろに対応して、金属板４１の端部（この例では、周縁部の３箇所）が圧入される。これにより、振動部材保持部７０に圧電ブザー４０が保持された状態になる。なお、斜線の範囲７１ｂ′，７２ｂ′のうち、右側壁１６の内面１６ｉと押さえリブ７１，７２の対向部分７１Ａ，７２Ａとの間に挟持されているのは、図８（Ａ）中に両矢印で示す領域１６ｉｘ内の部分に限られる。さらに、図１に示したように、上壁１１が下ハウジング１３（特に、側壁部１３Ｓ）に対して取り付けられる。この状態では、圧電ブザー４０の金属板４１の上縁が上壁１１の内面によって押さえられて、振動部材保持部７０から圧電ブザー４０が上方（図５中に矢印Ａ２で示した方向）へ離脱するのが規制される。これにより、右側壁１６の内面１６ｉに設けられた振動部材保持部７０に、圧電ブザー４０が確実に保持される。なお、仮に上壁１１よる規制が無い場合であっても、振動部材保持部７０に圧電ブザー４０が圧入されているので、金属板４１と右側壁１６の内面１６ｉとの間に摩擦力が生じて、振動部材保持部７０から圧電ブザー４０が離脱するのは抑制される。このようにして、血圧計１の完成状態では、右側壁１６の内面１６ｉの振動部材保持部７０に、圧電ブザー４０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で保持される。 In the process of assembling the sphygmomanometer 1, the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70 as shown by the arrow A1 in FIG. Then, first, the guide surfaces 71a1 and 72a1 shown in FIG. 7 guide the metal plate 41 of the piezoelectric buzzer 40 between the inner surfaces 16i (particularly the region 16ix) of the right side wall 16 and the pressing surfaces 71b and 72b. It leads to the gaps d1 and d2. Further, when the piezoelectric buzzer 40 is inserted under pressure, the peripheral edges of the metal plate 41 of the piezoelectric buzzer 40 (here, the left end and the right end protruding from the piezoelectric element layer 42) are press-fitted into the gaps d1 and d2. , Slide down. Further, when the piezoelectric buzzer 40 is inserted under pressure, the regulating surfaces 71d and 72d at the lower level of the pressing surfaces 71b and 72b regulate the piezoelectric buzzer 40 from being displaced to the left and to the right, respectively. (See FIG. 8 (A)). Further, the peripheral edge portion of the metal plate 41 of the piezoelectric buzzer 40 (here, the lower end portion protruding from the piezoelectric element layer 42) is press-fitted into the gap d3. Further, the stopper surface 73c3 regulates the downward movement of the piezoelectric buzzer 40. At this time, the pressing ranges 71b', 72b', 73c2'of the peripheral edge of the metal plate 41 of the piezoelectric buzzer 40, which are pressed by the pressing surfaces 71b, 72b, 73c2, are schematically shown by diagonal lines in FIG. (Note that FIG. 8B schematically shows the arrangement of the components of the vibrating member holding portion 70 with respect to the piezoelectric buzzer 40 in the same viewing direction as in FIG. 7). In this way, the end portion of the metal plate 41 (in this example, in this example, corresponds to the above-mentioned press-fitting margin in the gaps d1, d2, d3 defined by the inner surface 16i of the right side wall 16 and the pressing ribs 71, 72, 73. (3 locations on the peripheral edge) are press-fitted. As a result, the piezoelectric buzzer 40 is held by the vibrating member holding portion 70. Of the shaded areas 71b'and 72b', both are sandwiched between the inner surface 16i of the right side wall 16 and the facing portions 71A and 72A of the pressing ribs 71 and 72 in FIG. 8 (A). It is limited to the part within the area 16ix indicated by the arrow. Further, as shown in FIG. 1, the upper wall 11 is attached to the lower housing 13 (particularly, the side wall portion 13S). In this state, the upper edge of the metal plate 41 of the piezoelectric buzzer 40 is pressed by the inner surface of the upper wall 11, and the piezoelectric buzzer 40 is separated from the vibrating member holding portion 70 upward (in the direction indicated by the arrow A2 in FIG. 5). Is regulated. As a result, the piezoelectric buzzer 40 is securely held by the vibrating member holding portion 70 provided on the inner surface 16i of the right side wall 16. Even if there is no regulation by the upper wall 11, since the piezoelectric buzzer 40 is press-fitted into the vibrating member holding portion 70, a frictional force is generated between the metal plate 41 and the inner surface 16i of the right side wall 16. Therefore, it is suppressed that the piezoelectric buzzer 40 is separated from the vibrating member holding portion 70. In this way, in the completed state of the sphygmomanometer 1, the piezoelectric buzzer 40 is held by the vibrating member holding portion 70 on the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　したがって、この血圧計１では、圧電ブザー４０が制御部（図示せず）からリード配線４３，４４を介して電気信号を受けて振動すると、右側壁１６が振動して、ハウジング１０の外部へ音波が発せられる。つまり、右側壁１６の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。これにより、マイクロフォンを備えた外部端末と音波を介して通信が行われる。典型的な使用態様として、ハウジング１０がテーブル５００等の水平面上に置かれる場合、音波による通信状態を良好に保つことができる。特に、この例では、押圧面７１ｂ，７２ｂ，７３ｃ２によって圧電ブザー４０（金属板４１）が右側壁１６の内面１６ｉへ向けて押圧されるので、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 Therefore, in this sphygmomanometer 1, when the piezoelectric buzzer 40 receives an electric signal from the control unit (not shown) via the lead wirings 43 and 44 and vibrates, the right side wall 16 vibrates and a sound wave is emitted to the outside of the housing 10. Is emitted. That is, a relatively wide area (area) of the right side wall 16 can be vibrated to emit sound waves to the outside. As a result, communication is performed with an external terminal equipped with a microphone via sound waves. As a typical usage mode, when the housing 10 is placed on a horizontal surface such as a table 500, a good communication state by sound waves can be maintained. In particular, in this example, since the piezoelectric buzzer 40 (metal plate 41) is pressed toward the inner surface 16i of the right side wall 16 by the pressing surfaces 71b, 72b, 73c2, the vibration from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16 The transmission efficiency of the sound wave is increased, and the communication state by the sound wave can be maintained even better.
　さらに、この例では、圧電ブザー４０が圧入された状態で、金属板４１の平坦な第二の面４１ｂが、右側壁１６の内面１６ｉに面している。また、金属板４１の第二の面４１ｂに向けて側壁部１３Ｓの一部１６ｂｘが凹んだ形状を有している。これにより、右側壁１６の内面１６ｉのストライプ状の領域１６ｉｘが、金属板４１の第二の面４１ｂに対して平行面となって面接触している。したがって、圧電ブザー４０の振動がハウジング１０の側壁部１３Ｓに直接的に伝達される。この結果、振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 Further, in this example, with the piezoelectric buzzer 40 press-fitted, the flat second surface 41b of the metal plate 41 faces the inner surface 16i of the right side wall 16. Further, a part 16bx of the side wall portion 13S is recessed toward the second surface 41b of the metal plate 41. As a result, the striped region 16ix of the inner surface 16i of the right side wall 16 is in surface contact with the second surface 41b of the metal plate 41 as a parallel surface. Therefore, the vibration of the piezoelectric buzzer 40 is directly transmitted to the side wall portion 13S of the housing 10. As a result, the transmission efficiency of vibration is increased, and the communication state by sound waves can be maintained even better.
　また、圧電ブザー４０の圧電素子層４２が設けられている側では、大部分の領域（金属板４１の端部以外の領域）が、押さえリブ７１，７２，７３に覆われることなく、開放され得る。その場合、振動部材保持部７０（押さえリブ７１，７２，７３を含む）によって干渉されることなく、収容空間４００の内部に配置された制御部（図示せず）からリード配線４３，４４を介して、圧電素子層４２に対して信号としての電気信号を供給することができる。 Further, on the side of the piezoelectric buzzer 40 where the piezoelectric element layer 42 is provided, most of the region (the region other than the end of the metal plate 41) is opened without being covered by the pressing ribs 71, 72, 73. obtain. In that case, the control unit (not shown) arranged inside the accommodation space 400 is passed through the lead wirings 43 and 44 without being interfered by the vibrating member holding unit 70 (including the pressing ribs 71, 72 and 73). Therefore, an electric signal as a signal can be supplied to the piezoelectric element layer 42.
　また、この例では、圧電ブザー４０および押さえリブ７１，７２，７３は、右側壁１６の内面１６ｉに沿って配置されているので、嵩張らず、血圧計１の小型化に寄与することができる。 Further, in this example, since the piezoelectric buzzer 40 and the pressing ribs 71, 72, 73 are arranged along the inner surface 16i of the right side wall 16, they are not bulky and can contribute to the miniaturization of the sphygmomanometer 1.
　（変形例１）
　図９（Ａ）、図９（Ｂ）は、それぞれ上記振動部材保持部７０を変形した振動部材保持部（変形例１）１７０を、それぞれ圧電ブザー４０が保持された状態で、互いに別の方向から見たところを示している。なお、以下の各変形例の説明では、実施例１における構成要素と同じ構成要素には同じ符号を付し、実施例１における構成要素に対して変形された構成要素には順次１００ずつ増加した符号を付して、詳細な説明を省略する。 (Modification example 1)

　変形例１の振動部材保持部１７０は、上記スライド挿入方向（図５中に矢印Ａ１で示す）に垂直な方向に関して両側（すなわち図９（Ａ）、図９（Ｂ）において左右）に配置された一対の押さえリブ１７１，１７２と、スライド挿入の終端を画定するストッパを兼ねた押さえリブ１７３とを有している。 The vibrating member holding portions 170 of the first modification are arranged on both sides (that is, left and right in FIGS. 9A and 9B) with respect to the direction perpendicular to the slide insertion direction (indicated by the arrow A1 in FIG. 5). It has a pair of holding ribs 171 and 172, and holding ribs 173 that also serve as a stopper that defines the end of the slide insertion.
　この変形例１では、押さえリブ１７１，１７２，１７３は、右側壁１６の内面１６ｉに面して、押さえリブ７１，７２，７３の対向部分７１Ａ，７２Ａ，７３Ｂに代えて、それぞれ対向部分１７１Ａ，１７２Ａ，１７３Ａを有している。 In this modification 1, the pressing ribs 171, 172, and 173 face the inner surface 16i of the right side wall 16 and replace the opposing portions 71A, 72A, and 73B of the pressing ribs 71, 72, and 73, respectively. It has 172A and 173A.
　対向部分１７１Ａ，１７２Ａは、互いに左右対称な略Ｌ字状の断面を有して、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って延在している。対向部分１７１Ａ，１７２Ａの下部は、それぞれ右側壁１６と連なり一体に構成されている。それらの対向部分１７１Ａ，１７２Ａの上部は、それぞれ右側壁１６の内面１６ｉ（特に、領域１１６ｉｘ）との間に隙間ｄ１，ｄ２を形成している。また、対向部分１７３Ａは、略平板状の断面を有して、上記スライド挿入方向に沿って延在している。対向部分１７３Ａの下部は、右側壁１６と連なり一体に構成されている。その対向部分１７３Ａの上部は、右側壁１６の内面１６ｉ（特に、領域１１６ｉｘ）との間に隙間ｄ３を形成している。 The facing portions 171A and 172A have substantially L-shaped cross sections that are symmetrical with each other, and extend along the slide insertion direction (indicated by arrow A1 in FIG. 5). The lower portions of the facing portions 171A and 172A are connected to and integrally formed with the right side wall 16, respectively. The upper portions of the facing portions 171A and 172A form gaps d1 and d2 with the inner surface 16i (particularly, the region 116ix) of the right side wall 16, respectively. Further, the facing portion 173A has a substantially flat cross section and extends along the slide insertion direction. The lower part of the facing portion 173A is connected to the right side wall 16 and is integrally formed. The upper portion of the facing portion 173A forms a gap d3 with the inner surface 16i (particularly, the region 116ix) of the right side wall 16.
　図１０は、圧電ブザー４０が保持された状態の変形例１の振動部材保持部１７０を、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って上方から見たところを示している。この変形例１では、右側壁１６の内面１６ｉにおいてストライプ状に突出した領域１１６ｉｘは、実施例１における領域１６ｉｘに比して、左右方向の幅が狭く、領域１６ｉｘの約１／３程度の幅に設定されている。 FIG. 10 shows a view of the vibrating member holding portion 170 of the modified example 1 in a state where the piezoelectric buzzer 40 is held, as viewed from above along the slide insertion direction (indicated by the arrow A1 in FIG. 5). .. In the first modification, the striped region 116ix on the inner surface 16i of the right side wall 16 is narrower in the left-right direction than the region 16ix in the first embodiment, and is about one-third the width of the region 16ix. Is set to.
　図１０によって分かるように、押さえリブ１７１の対向部分１７１Ａは、右側壁１６の内面１６ｉとの間に、平坦な上面１７１ａ０のＬ字の長辺から、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面１７１ａ１と、この案内面１７１ａ１の下端から下方に延在する押圧面１７１ｂ１と、上記案内面１７１ａ１に交差し、平坦な上面１７１ａ０のＬ字の短辺から、右へ行くに伴って次第に高さが低くなるように傾斜した案内面１７１ａ２と、この案内面１７１ａ２の下端から下方に延在する規制面１７１ｂ２とを有している。押圧面１７１ｂ１は、振動部材保持部１７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した左端部）を押圧する。押圧面１７１ｂ１は、右側壁１６の内面１６ｉのストライプ状の領域１１６ｉｘから左方向に離間しているが、その領域１１６ｉｘに対して垂直な方向の隙間ｄ１を形成している。規制面１７１ｂ２は、圧電ブザー４０が左方向へ位置ずれするのを規制する（図１１（Ａ）参照）。案内面１７１ａ１，１７１ａ２は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ１に入るように案内する。対向部分１７１Ａは、押圧面１７１ｂの下方に位置する平坦面１７１ｃのレベルで、右側壁１６の内面１６ｉと連結されている。 As can be seen from FIG. 10, the height of the facing portion 171A of the pressing rib 171 gradually increases from the long side of the L-shape of the flat upper surface 171a0 to the inner surface 16i of the right side wall 16 as it approaches the inner surface 16i. From the short side of the L-shape of the flat upper surface 171a0 that intersects the guide surface 171a1 inclined so as to be low, the pressing surface 171b1 extending downward from the lower end of the guide surface 171a1, and the guide surface 171a1, to the right. It has a guide surface 171a2 that is inclined so that its height gradually decreases as it goes, and a regulation surface 171b2 that extends downward from the lower end of the guide surface 171a2. The pressing surface 171b1 presses the peripheral edge portion of the metal plate 41 (here, the left end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 170. The pressing surface 171b1 is separated from the striped region 116ix of the inner surface 16i of the right side wall 16 in the left direction, but forms a gap d1 in the direction perpendicular to the region 116ix. The regulation surface 171b2 regulates the piezoelectric buzzer 40 from being displaced to the left (see FIG. 11A). When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surfaces 171a1 and 171a2 guide the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d1. The facing portion 171A is connected to the inner surface 16i of the right side wall 16 at the level of the flat surface 171c located below the pressing surface 171b.
　同様に、図１０中に示す押さえリブ１７２の対向部分１７２Ａも、右側壁１６の内面１６ｉとの間に、平坦な上面１７２ａ０のＬ字の長辺から、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面１７２ａ１と、この案内面１７２ａ１の下端から下方に延在する押圧面１７２ｂ１と、上記案内面１７２ａ１に交差し、平坦な上面１７２ａ０のＬ字の短辺から、左へ行くに伴って次第に高さが低くなるように傾斜した案内面１７２ａ２と、この案内面１７２ａ２の下端から下方に延在する規制面１７２ｂ２とを有している。押圧面１７２ｂ１は、振動部材保持部１７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した右端部）を押圧する。押圧面１７２ｂ１は、右側壁１６の内面１６ｉのストライプ状の領域１１６ｉｘから右方向に離間しているが、その領域１１６ｉｘに対して垂直な方向の隙間ｄ２を形成している。規制面１７２ｂ２は、圧電ブザー４０が右方向へ位置ずれするのを規制する（図１１（Ａ）参照）。案内面１７２ａ１，１７２ａ２は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ２に入るように案内する。対向部分１７２Ａは、押圧面１７２ｂの下方に位置する平坦面１７２ｃのレベルで、右側壁１６の内面１６ｉと連結されている。 Similarly, the facing portion 172A of the pressing rib 172 shown in FIG. 10 also gradually increases in height from the long side of the L-shape of the flat upper surface 172a0 to the inner surface 16i of the right side wall 16 as it approaches the inner surface 16i. From the short side of the L-shape of the flat upper surface 172a0 that intersects the guide surface 172a1 inclined so as to be low, the pressing surface 172b1 extending downward from the lower end of the guide surface 172a1, and the guide surface 172a1 to the left. It has a guide surface 172a2 that is inclined so that its height gradually decreases as it goes to, and a regulation surface 172b2 that extends downward from the lower end of the guide surface 172a2. The pressing surface 172b1 presses the peripheral edge portion of the metal plate 41 (here, the right end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 170. The pressing surface 172b1 is separated to the right from the striped region 116ix of the inner surface 16i of the right side wall 16, but forms a gap d2 in the direction perpendicular to the region 116ix. The regulation surface 172b2 regulates the piezoelectric buzzer 40 from being displaced to the right (see FIG. 11A). When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surfaces 172a1 and 172a2 guide the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d2. The facing portion 172A is connected to the inner surface 16i of the right side wall 16 at the level of the flat surface 172c located below the pressing surface 172b.
　図１０中に示す押さえリブ１７３の対向部分１７３Ａは、右側壁１６の内面１６ｉとの間に、平坦な上面１７３ｃ０のレベルから、内面１６ｉに近づくに伴って次第に高さが低くなるように傾斜した案内面１７３ｃ１と、この案内面１７３ｃ１の下端から下方に延在する押圧面１７３ｃ２と、上記スライド挿入の終端を画定するストッパ面１７３ｃ３とを有している。押圧面１７３ｃ２は、振動部材保持部７０に圧電ブザー４０が保持された状態では、金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した下端部）を押圧する。押圧面１７３ｃ２は、右側壁１６の内面１６ｉのストライプ状の領域１１６ｉｘとの間に、その領域１１６ｉｘに対して垂直な方向の隙間ｄ３を形成している。案内面１７３ｃ１は、振動部材保持部７０に圧電ブザー４０がスライド挿入されるとき、圧電ブザー４０の金属板４１の周縁部が円滑に隙間ｄ３に入るように案内する。ストッパ面１７３ｃ３は、スライド挿入される圧電ブザー４０に当接して、圧電ブザー４０のスライド挿入を停止させる（図１１（Ａ）参照）。 The facing portion 173A of the pressing rib 173 shown in FIG. 10 is inclined from the level of the flat upper surface 173c0 to the inner surface 16i of the right side wall 16 so as to gradually decrease in height as it approaches the inner surface 16i. It has a guide surface 173c1, a pressing surface 173c2 extending downward from the lower end of the guide surface 173c1, and a stopper surface 173c3 defining the end of the slide insertion. The pressing surface 173c2 presses the peripheral edge portion of the metal plate 41 (here, the lower end portion protruding from the piezoelectric element layer 42) in a state where the piezoelectric buzzer 40 is held by the vibrating member holding portion 70. The pressing surface 173c2 forms a gap d3 in the direction perpendicular to the region 116ix between the pressing surface 173c2 and the striped region 116ix of the inner surface 16i of the right side wall 16. When the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 70, the guide surface 173c1 guides the peripheral portion of the metal plate 41 of the piezoelectric buzzer 40 so as to smoothly enter the gap d3. The stopper surface 173c3 abuts on the piezoelectric buzzer 40 to be slide-inserted to stop the slide insertion of the piezoelectric buzzer 40 (see FIG. 11 (A)).
　血圧計１の組立過程では、図５中に矢印Ａ１で示すように、振動部材保持部１７０に、圧電ブザー４０がスライド挿入される。すると、まず、図１０中に示した案内面１７１ａ１，１７１ａ２；１７２ａ１，１７２ａ２が圧電ブザー４０の金属板４１を案内して、右側壁１６の内面１６ｉに垂直な方向に関して右側壁１６の内面１６ｉのストライプ状の領域１１６ｉｘと押圧面１７１ｂ１，１７２ｂ１との間に導くとともに、左右方向に関して規制面１７１ｂ２と規制面１７２ｂ２との間に導く。さらに、圧電ブザー４０が圧力をかけて挿入されると、圧電ブザー４０の金属板４１が全体として隙間ｄ１，ｄ２に圧入され、下方へスライドする。このとき、規制面１７１ｂ２，１７２ｂ２は、それぞれ圧電ブザー４０が左方向、右方向へ位置ずれするのを規制する（図１１（Ａ）参照）。さらに、圧電ブザー４０が圧力をかけて挿入されると、圧電ブザー４０の金属板４１の周縁部（ここでは、圧電素子層４２からはみ出した下端部）が隙間ｄ３に圧入される。また、ストッパ面１７３ｃ３が圧電ブザー４０の下方への動きを規制する。このとき、押圧面１７１ｂ１，１７２ｂ１，１７３ｃ２が圧電ブザー４０の金属板４１の周縁部のうち押圧する範囲１７１ｂ１′，１７２ｂ１′，１７３ｃ２′を、図１１（Ａ）中に斜線で模式的に示している（なお、図１１（Ｂ）は、圧電ブザー４０に対する振動部材保持部１７０の構成要素の配置を、図１０におけるのと同じ視方向で模式的に示している。）。このように、右側壁１６の内面１６ｉと押さえリブ１７１，１７２，１７３とが画定する隙間ｄ１，ｄ２，ｄ３に、既述の圧入しろに対応して、金属板４１が全体として圧入される。これにより、振動部材保持部１７０に圧電ブザー４０が保持された状態になる。さらに、図１に示したように、上壁１１が下ハウジング１３（特に、側壁部１３Ｓ）に対して取り付けられる。この状態では、圧電ブザー４０の金属板４１の上縁が上壁１１の内面によって押さえられて、振動部材保持部１７０から圧電ブザー４０が上方（図５中に矢印Ａ２で示した方向）へ離脱するのが規制される。これにより、右側壁１６の内面１６ｉに設けられた振動部材保持部１７０に、圧電ブザー４０が確実に保持される。なお、仮に上壁１１よる規制が無い場合であっても、振動部材保持部１７０に圧電ブザー４０が圧入されているので、金属板４１と右側壁１６の内面１６ｉとの間に摩擦力が生じて、振動部材保持部１７０から圧電ブザー４０が離脱するのは抑制される。このようにして、血圧計１の完成状態では、右側壁１６の内面１６ｉの振動部材保持部１７０に、圧電ブザー４０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で保持される。 In the process of assembling the sphygmomanometer 1, the piezoelectric buzzer 40 is slide-inserted into the vibrating member holding portion 170 as shown by the arrow A1 in FIG. Then, first, the guide surfaces 171a1,171a2; 172a1,172a2 shown in FIG. 10 guide the metal plate 41 of the piezoelectric buzzer 40, and the inner surface 16i of the right side wall 16 with respect to the direction perpendicular to the inner surface 16i of the right side wall 16. It is guided between the striped region 116ix and the pressing surfaces 171b1, 172b1 and between the regulation surface 171b2 and the regulation surface 172b2 in the left-right direction. Further, when the piezoelectric buzzer 40 is inserted under pressure, the metal plate 41 of the piezoelectric buzzer 40 is press-fitted into the gaps d1 and d2 as a whole and slides downward. At this time, the regulation surfaces 171b2 and 172b2 restrict the piezoelectric buzzer 40 from being displaced to the left and right, respectively (see FIG. 11A). Further, when the piezoelectric buzzer 40 is inserted under pressure, the peripheral edge portion of the metal plate 41 of the piezoelectric buzzer 40 (here, the lower end portion protruding from the piezoelectric element layer 42) is press-fitted into the gap d3. Further, the stopper surface 173c3 regulates the downward movement of the piezoelectric buzzer 40. At this time, the pressing ranges 171b1', 172b1', and 173c2'of the peripheral edge of the metal plate 41 of the piezoelectric buzzer 40, which are pressed by the pressing surfaces 171b1, 172b1, 173c2, are schematically shown by diagonal lines in FIG. (Note that FIG. 11B schematically shows the arrangement of the components of the vibrating member holding portion 170 with respect to the piezoelectric buzzer 40 in the same viewing direction as in FIG. 10). In this way, the metal plate 41 is press-fitted into the gaps d1, d2, d3 defined by the inner surface 16i of the right side wall 16 and the pressing ribs 171, 172, 173 as a whole, corresponding to the above-mentioned press-fitting margin. As a result, the piezoelectric buzzer 40 is held by the vibrating member holding portion 170. Further, as shown in FIG. 1, the upper wall 11 is attached to the lower housing 13 (particularly, the side wall portion 13S). In this state, the upper edge of the metal plate 41 of the piezoelectric buzzer 40 is pressed by the inner surface of the upper wall 11, and the piezoelectric buzzer 40 is separated from the vibrating member holding portion 170 upward (in the direction indicated by the arrow A2 in FIG. 5). Is regulated. As a result, the piezoelectric buzzer 40 is securely held by the vibrating member holding portion 170 provided on the inner surface 16i of the right side wall 16. Even if there is no regulation by the upper wall 11, since the piezoelectric buzzer 40 is press-fitted into the vibrating member holding portion 170, a frictional force is generated between the metal plate 41 and the inner surface 16i of the right side wall 16. Therefore, it is suppressed that the piezoelectric buzzer 40 is separated from the vibrating member holding portion 170. In this way, in the completed state of the sphygmomanometer 1, the piezoelectric buzzer 40 is held by the vibrating member holding portion 170 on the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　したがって、この変形例１では、実施例１におけるのと同様に、圧電ブザー４０が制御部（図示せず）からリード配線４３，４４を介して電気信号を受けて振動すると、右側壁１６が振動して、ハウジング１０の外部へ音波が発せられる。つまり、右側壁１６の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。 Therefore, in this modification 1, when the piezoelectric buzzer 40 receives an electric signal from the control unit (not shown) via the lead wirings 43 and 44 and vibrates as in the first embodiment, the right side wall 16 vibrates. Then, a sound wave is emitted to the outside of the housing 10. That is, a relatively wide area (area) of the right side wall 16 can be vibrated to emit sound waves to the outside.
　また、この変形例１では、上述のように、右側壁１６の内面１６ｉにおいてストライプ状に突出した領域１１６ｉｘは、実施例１における領域１６ｉｘに比して、左右方向の幅が狭く、約１／３程度に設定されている。それに応じて、実施例１におけるストライプ状の空間１６ｉｃ，１６ｉｄに比して、図１０によって分かるように、その領域１１６ｉｘの左右両側のストライプ状の空間１１６ｉｃ，１１６ｉｄが拡張されている。したがって、下ハウジング１３を合成樹脂の一体成形により作製するための金型において、微細な部分が少なくなる。したがって、合成樹脂の一体成形により、下ハウジング１３を作製し易くなる。 Further, in the first modification, as described above, the striped region 116ix on the inner surface 16i of the right side wall 16 is narrower in the left-right direction than the region 16ix in the first embodiment, and is about 1 /. It is set to about 3. Correspondingly, as can be seen from FIG. 10, the striped spaces 116ic and 116id on both the left and right sides of the region 116ix are expanded as compared with the striped spaces 16ic and 16id in the first embodiment. Therefore, in the mold for manufacturing the lower housing 13 by integrally molding the synthetic resin, the number of fine parts is reduced. Therefore, the lower housing 13 can be easily manufactured by integrally molding the synthetic resin.
　（変形例２）
　図１２（Ａ）、図１２（Ｂ）は、上述の変形例１においてハウジング１０の上壁１１に工夫を加えた例（変形例２）を示している。図１２（Ａ）は、上壁１１が下ハウジング１３（特に、側壁部１３Ｓ）に対して装着された状態で、圧電ブザー４０を保持した状態の振動部材保持部１７０を、斜め下方から見たところを示している。図１２（Ｂ）は、その振動部材保持部１７０を通り、圧電ブザー４０に対して垂直な断面を、斜め上方から見たところを示している。 (Modification 2)
12 (A) and 12 (B) show an example (deformed example 2) in which the upper wall 11 of the housing 10 is devised in the above-mentioned modified example 1. In FIG. 12A, the vibrating member holding portion 170 holding the piezoelectric buzzer 40 with the upper wall 11 mounted on the lower housing 13 (particularly, the side wall portion 13S) is viewed from diagonally below. However, it shows. FIG. 12B shows a cross section perpendicular to the piezoelectric buzzer 40 as viewed from diagonally above through the vibrating member holding portion 170.
　この変形例２では、ハウジング１０の上壁１１と一体に、弾性を示す弾性突起１６１と、互いに左右対称な一対の規制リブ１６２，１６３とが設けられている。 In this modification 2, an elastic protrusion 161 exhibiting elasticity and a pair of regulatory ribs 162 and 163 symmetrical with each other are provided integrally with the upper wall 11 of the housing 10.
　上壁１１には、圧電ブザー４０の圧電素子層４２に面する位置に、上壁１１を厚さ方向に貫通する矩形の窓１１ｗが設けられている。弾性突起１６１は、上壁１１のうち窓１１ｗの縁部（圧電ブザー４０から遠い側の縁部）から、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って下方へ平板状に延在する根元部１６１ａと、この根元部１６１ａに連なり、圧電ブザー４０へ向かって湾曲した板状の湾曲部１６１ｂと、この湾曲部１６１ｂに連なり、圧電ブザー４０へ向かって上方へ平板状に延在する接近部１６１ｃと、この接近部１６１ｃの先端に設けられ、圧電ブザー４０の圧電素子層４２に当接する当接部１６１ｄとを有している。上壁１１の内面１１ｉと根元部１６１ａの各縁との間にまたがって、それぞれ弾性突起１６１の弾性（ばね定数）を高める（調節する）ためのフランジ部１６１ｅ，１６１ｆが設けられている。当接部１６１ｄの先端は、圧電素子層４２を損傷しないように、半円筒状に丸く形成されている。規制リブ１６２，１６３は、振動部材保持部１７０に保持された圧電ブザー４０の、図１２（Ａ）において左右斜め上方に配置されている。規制リブ１６２は、圧電ブザー４０の金属板４１の周縁部に斜め上方から対向する規制面１６２ａを有する。この点、規制リブ１６３も同様である。 The upper wall 11 is provided with a rectangular window 11w that penetrates the upper wall 11 in the thickness direction at a position facing the piezoelectric element layer 42 of the piezoelectric buzzer 40. The elastic protrusion 161 is flattened downward from the edge of the window 11w (the edge on the side far from the piezoelectric buzzer 40) of the upper wall 11 along the slide insertion direction (indicated by the arrow A1 in FIG. 5). An extending root portion 161a, a plate-shaped curved portion 161b connected to the root portion 161a and curved toward the piezoelectric buzzer 40, and a plate-shaped curved portion 161b connected to the curved portion 161b and extending upward in a flat plate shape toward the piezoelectric buzzer 40. It has an existing approaching portion 161c and an abutting portion 161d provided at the tip of the approaching portion 161c and in contact with the piezoelectric element layer 42 of the piezoelectric buzzer 40. Flange portions 161e and 161f for increasing (adjusting) the elasticity (spring constant) of the elastic protrusions 161 are provided between the inner surface 11i of the upper wall 11 and each edge of the root portion 161a, respectively. The tip of the contact portion 161d is formed in a semi-cylindrical round shape so as not to damage the piezoelectric element layer 42. The regulating ribs 162 and 163 are arranged diagonally upward to the left and right in FIG. 12A of the piezoelectric buzzer 40 held by the vibrating member holding portion 170. The regulation rib 162 has a regulation surface 162a that faces the peripheral edge of the metal plate 41 of the piezoelectric buzzer 40 from diagonally above. In this respect, the same applies to the regulation rib 163.
　血圧計１の完成状態では、図１２（Ｂ）中に示すように、上壁１１の弾性突起１６１から押圧力Ｆ０を受けて、圧電ブザー４０が右側壁１６の内面１６ｉ（特に、領域１１６ｉｘ）へ向けて付勢され、押し付けられる。したがって、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the completed state of the sphygmomanometer 1, as shown in FIG. 12B, the piezoelectric buzzer 40 receives the pressing force F0 from the elastic projection 161 of the upper wall 11 and the piezoelectric buzzer 40 receives the pressing force F0 from the inner surface 16i of the right side wall 16 (particularly, the region 116ix). It is urged and pressed toward. Therefore, the efficiency of transmitting vibration from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16 is increased, and the communication state by sound waves can be maintained even better.
　また、規制リブ１６２，１６３によって、圧電ブザー４０が上方（図５中に矢印Ａ２で示した方向）へ離脱するのが規制される。これにより、右側壁１６の内面１６ｉに設けられた振動部材保持部１７０に、圧電ブザー４０が確実に保持される。 Further, the regulation ribs 162 and 163 restrict the piezoelectric buzzer 40 from being separated upward (in the direction indicated by the arrow A2 in FIG. 5). As a result, the piezoelectric buzzer 40 is securely held by the vibrating member holding portion 170 provided on the inner surface 16i of the right side wall 16.
　（変形例３）
　図１３（Ａ）、図１３（Ｂ）、は、上記圧電ブザー４０が保持された状態の振動部材保持部２７０の近傍に、配線経路２７８が含まれた構造例（変形例３）を、それぞれ斜め上方から互いに別の角度で見たところを示している。図１３（Ｃ）は、その構造例を、上記スライド挿入方向（図５中に矢印Ａ１で示す）に沿って上方から見たところを示している。図１４（Ａ）、図１４（Ｂ）、図１４（Ｃ）は、上記配線経路２７８に、上記圧電ブザー４０に接する第１電極端子としての第１ばね端子Ｗ１、第２電極端子としての第２ばね端子Ｗ２が設けられた状態を、それぞれ図１３（Ａ）、図１３（Ｂ）、図１３（Ｃ）に対応して示している。この変形例３では、既述のリード配線４３，４４は省略されている。 (Modification example 3)
13 (A) and 13 (B) show structural examples (modification example 3) in which the wiring path 278 is included in the vicinity of the vibrating member holding portion 270 in which the piezoelectric buzzer 40 is held. It shows the views from diagonally above at different angles. FIG. 13C shows an example of the structure viewed from above along the slide insertion direction (indicated by arrow A1 in FIG. 5). 14 (A), 14 (B), and 14 (C) show the first spring terminal W1 as the first electrode terminal in contact with the piezoelectric buzzer 40 and the second electrode terminal as the second electrode terminal in the wiring path 278. The state in which the two spring terminals W2 are provided is shown corresponding to FIGS. 13 (A), 13 (B), and 13 (C), respectively. In this modification 3, the lead wirings 43 and 44 described above are omitted.
　図１３（Ａ）、図１３（Ｂ）、図１３（Ｃ）によって分かるように、この変形例３では、実施例１の振動部材保持部７０に代えて、振動部材保持部２７０を備えている。この振動部材保持部２７０は、上記スライド挿入方向（図５中に矢印Ａ１で示す）に垂直な方向に関して両側（すなわち図１３（Ａ）、図１３（Ｂ）、図１３（Ｃ）において左右）に配置された一対の押さえリブ２７１，２７２と、スライド挿入の終端を画定するストッパを兼ねた押さえリブ２７３とを有している。右側壁１６の内面１６ｉと押さえリブ２７１，２７２，２７３とが画定する隙間ｄ１，ｄ２，ｄ３に、既述の圧入しろに対応して、圧電ブザー４０（金属板４１）が圧入されている。これにより、右側壁１６の内面１６ｉの振動部材保持部２７０に、圧電ブザー４０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で保持されている。 As can be seen from FIGS. 13 (A), 13 (B), and 13 (C), in this modified example 3, the vibrating member holding portion 270 is provided instead of the vibrating member holding portion 70 of the first embodiment. .. The vibrating member holding portion 270 is provided on both sides (that is, left and right in FIGS. 13 (A), 13 (B), and 13 (C)) with respect to a direction perpendicular to the slide insertion direction (indicated by arrow A1 in FIG. 5). It has a pair of holding ribs 271,272 arranged in the above, and holding ribs 273 that also serve as a stopper that defines the end of the slide insertion. A piezoelectric buzzer 40 (metal plate 41) is press-fitted into the gaps d1, d2, and d3 defined by the inner surface 16i of the right side wall 16 and the pressing ribs 271, 272, and 273, corresponding to the above-mentioned press-fitting margin. As a result, the piezoelectric buzzer 40 is held by the vibrating member holding portion 270 on the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　なお、この変形例３では、右側壁１６の内面１６ｉにおいてストライプ状に突出した領域２１６ｉｘは、変形例１における領域１１６ｉｘに比して、さらに左右方向の幅が狭く、領域１１６ｉｘの約１／２程度の幅に設定されている。右側壁１６のうち振動部材保持部２７０に対応する部分２１６ｂｘは、圧電ブザー４０へ向けて凹んでおらず、平坦になっている。この態様であっても、圧電ブザー４０の振動を右側壁１６に伝達させることができる。 In the modified example 3, the striped region 216ix on the inner surface 16i of the right side wall 16 is narrower in the left-right direction than the region 116ix in the modified example 1, and is about 1/2 of the region 116ix. It is set to a width of about. The portion 216bx of the right side wall 16 corresponding to the vibrating member holding portion 270 is not recessed toward the piezoelectric buzzer 40 and is flat. Even in this embodiment, the vibration of the piezoelectric buzzer 40 can be transmitted to the right side wall 16.
　この変形例３では、振動部材保持部２７０の近傍に、より詳しくは、収容空間４００の振動部材保持部２７０よりも内側の位置に、配線経路２７８が設けられている。図１３（Ｃ）によって分かるように、この配線経路２７８は、収容空間４００の内部から、圧電ブザー４０の金属板４１に達する第１の配線経路（１点鎖線で示す）Ｃ１と、圧電ブザー４０の圧電素子層４２に達する第２の配線経路（破線で示す）Ｃ２とを含んでいる。第１の配線経路Ｃ１は、ストライプ状の領域２１６ｉｘの前方の位置で、サブ経路Ｃ１ａとサブ経路Ｃ１ｂとの２つに分岐している。これらのサブ経路Ｃ１ａ、サブ経路Ｃ１ｂは、それぞれ金属板４１の周縁部の左端部、右端部に達している。第２の配線経路Ｃ２は、収容空間４００の内部からサブ経路Ｃ１ｂの右方を通り、サブ経路Ｃ１ｂの下方をくぐって（図１３（Ｂ）参照）、圧電素子層４２に達している。理解の容易のため、第２の配線経路Ｃ２の先端は、符号Ｃ２ｔで示されている。 In this modification 3, the wiring path 278 is provided in the vicinity of the vibrating member holding portion 270, more specifically, at a position inside the vibrating member holding portion 270 of the accommodation space 400. As can be seen from FIG. 13C, the wiring path 278 includes a first wiring path (indicated by an alternate long and short dash line) C1 reaching the metal plate 41 of the piezoelectric buzzer 40 from the inside of the accommodation space 400, and the piezoelectric buzzer 40. Includes a second wiring path (shown by a broken line) C2 that reaches the piezoelectric element layer 42 of the above. The first wiring path C1 is branched into two subpaths C1a and C1b at a position in front of the striped region 216ix. These sub-paths C1a and C1b reach the left end and the right end of the peripheral edge of the metal plate 41, respectively. The second wiring path C2 passes from the inside of the accommodation space 400 to the right side of the sub path C1b, passes under the sub path C1b (see FIG. 13B), and reaches the piezoelectric element layer 42. For ease of understanding, the tip of the second wiring path C2 is indicated by the reference numeral C2t.
　これらの第１の配線経路Ｃ１、第２の配線経路Ｃ２に沿って、図１４（Ａ）、図１４（Ｂ）、図１４（Ｃ）に示すように、それぞれ弾性をもつ金属からなる第１ばね端子Ｗ１、第２ばね端子Ｗ２が設けられる。第１ばね端子Ｗ１は、ストライプ状の領域２１６ｉｘの前方の位置で、サブ端子部Ｗ１ａとサブ端子部Ｗ１ｂとの２つに分岐している。これらのサブ端子部Ｗ１ａ、サブ端子部Ｗ１ｂは、それぞれ金属板４１の周縁部の左端部、右端部に達している。第２ばね端子Ｗ２は、収容空間４００の内部からサブ端子部Ｗ１ｂの右方を通り、サブ端子部Ｗ１ｂの下方をくぐって、圧電素子層４２に達している。サブ端子部Ｗ１ａ、サブ端子部Ｗ１ｂの先端近傍は、それぞれ縦方向に屈曲されており、屈曲された端部Ｗ１ａｔ、Ｗ１ｂｔがそれぞれ金属板４１の周縁部の左端部、右端部に当接している。第２ばね端子Ｗ２の先端近傍は、横方向に屈曲されており、屈曲された端部Ｗ２ｔが圧電素子層４２に当接している。これにより、収容空間４００の内部に設けられた制御部（図示せず）から、圧電ブザー４０に対して電気信号が供給される。 Along the first wiring path C1 and the second wiring path C2, as shown in FIGS. 14 (A), 14 (B), and 14 (C), the first one made of an elastic metal, respectively. A spring terminal W1 and a second spring terminal W2 are provided. The first spring terminal W1 is branched into two, a sub terminal portion W1a and a sub terminal portion W1b, at a position in front of the striped region 216ix. These sub-terminal portions W1a and sub-terminal portions W1b reach the left end portion and the right end portion of the peripheral edge portion of the metal plate 41, respectively. The second spring terminal W2 passes from the inside of the accommodation space 400 to the right side of the sub terminal portion W1b, passes under the sub terminal portion W1b, and reaches the piezoelectric element layer 42. The vicinity of the tips of the sub terminal portion W1a and the sub terminal portion W1b are respectively bent in the vertical direction, and the bent ends W1at and W1bt are in contact with the left end and the right end of the peripheral edge of the metal plate 41, respectively. .. The vicinity of the tip of the second spring terminal W2 is bent in the lateral direction, and the bent end W2t is in contact with the piezoelectric element layer 42. As a result, an electric signal is supplied to the piezoelectric buzzer 40 from a control unit (not shown) provided inside the accommodation space 400.
　第１ばね端子Ｗ１、第２ばね端子Ｗ２は、それぞれ弾性を有し、圧電ブザー４０に当接して、図１４（Ｃ）中に示す押圧力Ｆ１，Ｆ２，Ｆ３で、右側壁１６の内面１６ｉへ向かう向きに付勢する。これにより、圧電ブザー４０が右側壁１６の内面１６ｉに押し付けられる。したがって、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 The first spring terminal W1 and the second spring terminal W2 each have elasticity and abut on the piezoelectric buzzer 40, and the pressing pressures F1, F2, and F3 shown in FIG. 14C are applied to the inner surface 16i of the right side wall 16. Elevate in the direction toward. As a result, the piezoelectric buzzer 40 is pressed against the inner surface 16i of the right side wall 16. Therefore, the efficiency of transmitting vibration from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16 is increased, and the communication state by sound waves can be maintained even better.
